Best cooling for DDR2 mem ?

Water would be the best option, but doing so creates challenges that would require special measures to overcome loop-wise. As for my RAM, it's cooled by my rads exhaust, and further helped by 2 120mm exhaust fans that pull air across my MB.

what ram do u need to cool? i dont think any ddr2 or ddr3 ram running at spec speeds need any special cooling.

Tell that to all the D9 users who are tired of replacing their sticks repeatedly.

Even at stock speeds, keeping the sticks cool will allow them to live longer.

amen to this.

ive lost 4 pairs of my tracers. If your the type to push them hard active cooling is a must.
 
Cotsco sells window AC units for a $100. Open computer case, have the AC blow directly into it....

But usually good airflow inside your case will do the trick..
 
1) Pressurize case with SUM(intake_CFMs) > SUM(exhaust_CFMs)
2) Build ducts to get CPU exhaust air out of case without mixing
3) Cut a flat duct-plate to cover mobo about 1/4" clearance with top of RAM modules
4) Deploy exhaust fan to pull air between the mobo and the duct-plate, and arrange to have air pulled past the RAM

This will also suggest a means of cooling your chipset and Mosfets.
 
Tullphan --

I posted the following thread last year, with links to several pictures, etc.

Motherboard Ducting from the Bonzai-Duck-t-ster

What was shown here is just preliminary prototype. The ducts were rebuilt using Lexan together with the foam-art-board. Those pictures I also recall posting, possibly in a long thread a year ago about the TR Ultima 90.
 
Best way to reduce memory temps... lower VDIMM. 😀 Someone's got to point that out, right?

The crucial ballistix did not die due to heat. although some may have, their problem was just poor QC. many were DOA and some died running under specified timings and voltages.

speaking from personal exp, i've purchased 4 x 1gb of ballistix and it gave me a headache. only one of the 4 original ones passed memtest86+ and 3 more of the RMA'ed ones did NOT pass 24 hours of memtest86+. testing was done under specified voltages, speeds, and timings.
i did have adequate cooling on them to not even feel warm on the heatspreader.

 
Much of the Ballistix problem was heat. Their poor heatspreaders not touching the ram modules was 90% of the problem. Google Ballistix Heatspreader and you'll see countless examples.
 
I had an exchange with Aigomorla about this last year. As he said, he lost about four pairs of Tracers. But the point of the discussion was "safe voltage level."

So he who made a remark about QC -- LOUISSSSS ??!! -- hit the nail in the head.

Let me explain. The warranty maximum voltage in the Ballistix or Tracer models was 2.2V.

Now -- depending on the motherboard -- you might have a bias in the way "set" and "monitored" voltages are read or implemented. On the other hand, there may be a decent calibration between "set" and "monitored." And both Aigo and myself were using 680i motherboards last year with the Crucials.

My experience -- I set the voltage to 2.175V. The warranty limit, as I said, was 2.2V. The monitored voltage was 2.204 to 2.21V. And my aircooling solution keeps my components pretty frosty, or at least as cool as it could get with sets of air pressure, ambient-temperature, direction and volume. 2.175 set voltage was enough to contribute at least partially to my crucial failure.

On the other hand, I was also running my Crucials at a 1T Command Rate. When, eventually, after receiving my replacement set under lifetime warranty, I had some subsequent correspondence with their support staff, they absolutely went BALLISTIC when I told them I'd been running them at a 1T command rate. And -- in fact -- the topic came up when I asked them why I couldn't run the replacement set at 1T. They would only run at 2T.

Like I said -- they went Ballistic -- citing threat of warranty cancellation.
